Shrikumar Sharma 795cca3ec6 Prestaging package group and package filter
A new prestaging package group and package filter is created
for prestaging operations. It has fewer packages than the
platform-storage package group. Currently, 785 packages
are installed.

Test Plan:

PASS: Verify the creation of a new packagegroup,
      platform-prestaging, in the comps.xml file under the
      repodata directory of the prestage iso.

PASS: Verify that the number of packages to be installed
      decreases, when valid entries are included in the file
      filter_out_from_prestaging.
